denary

In other words, the denary scale, though adopted in notation and in numeration, does not arise in the corresponding mental concept until we get beyond 100.

Among the Tartars and Thibetians, the signs of the denary cycle are expressed by the names of the five elements repeated twice, or by the names of the five colours with their shades. 

It is unnecessary for us ordinarily to state that we are using the denary scale, because this is always understood in the common affairs of life.

Each one was worth a denary, which was a coin worth about a shilling, or a quarter of a dollar.

In consequence of this limitation of the power of perception of number, it is practically impossible to use a pure denary scale in elementary number-teaching.
